This is a smart power quality analyzer that measures single-phase and three-phase system variables (W, Wdmd, var, VA, VAdmd, PF, PFavg, V, A, An dmd). It has a graphical display, 4x4-bit instantaneous variable readout, 4x9-digit total energy readout, 4x6-digit partial energy readout, 48 independent energy meters to be used as single, dual, multi-time energy management.
The WM3-96 modular smart power quality analyzer provides comprehensive measurement of voltage, current, power, energy, and harmonic distortion for single‑phase and three‑phase systems. It features a 128×64‑dot LCD, IP65 front protection, and a universal power supply ranging from 18 VAC/DC to 260 VAC/DC.
The device supports up to four optional analog outputs, digital outputs, pulse outputs, and alarm setpoints, all programmable via RS‑422/485 or MODBUS RTU. Sampling is performed at 6400 samples/s with temperature drift under 200 ppm/°C, and data can be logged with optional RS‑232/RTC modules.
